One of the most improved comedies of last season, Fox’s “The Mindy Project,” returns on Sept. 17 at 9:30/8:30c for its second-season premiere. Everyone’s favorite OB-GYN, Mindy Lahiri (Mindy Kaling), has embarked on a trip of self-discovery doing good in Haiti with her boyfriend, Casey (Anders Holm), but the practice she left behind is thriving in New York City thanks to Dr. Paul Leotard (James Franco), the miracle-worker doctor with model-good looks — seriously, he was actually a model.
